1. What is a modular room?

Not everyone is familiar with the concept of modular Coldrooms.

Basically put, a modular coldroom is refrigeration room whose walls, ceiling and floor

is composed of various sections or modules. These modules all fit together and lock

into place providing a thermally insulated and structurally sound room.

Bromic Coldrooms are composed of modules 85mm thick.

As customers may not always use standard refrigeration equipment, all Bromic

Coldrooms are shipped with uncut panels.

The cutting and/or drilling for the placement of refrigeration units as well as pressure

balance valves should be conducted by the installer.

2. Concept and benefits:

The fundamental concept of Coldkit Coldrooms resides in the size of the modules and

placement of their interlocking cam mechanisms.

Our standard modular Coldrooms can be composed of ceiling and wall panels of the

following widths: 40cm, 80cm, 120cm. Floor panels are only available in widths of

80cm and 120cm.

The heights of standard wall panels are either 200cm or 220cm.

All panels interlock with special cam-locks, which align and lock onto each other.

Bromic rooms may be used as freezers as well as chillers. For temperatures at or

below freezing the door must have a heating cord and is referred to as a ‘negative

door’. We also recommend that you place a pressure balance valve through one of

the walls in order to equalise internal and external pressure.

Bromic Coldrooms all have 85mm thick floors.

3. Setup Requirements

Before starting make sure there is sufficient space is available for room assembly, a

relevant power outlet is installed and the installation surface is flat and level.

3.1 Power Requirements

Power requirements vary for the different room sizes and between cool and freezer as

shown in the Table below.

*Size = Length x Width in Metres

Note: Power requirements are based on usage of standard slide-in

refrigeration system selected by Bromic for a general usage coldroom.

Altering or changing this unit can potentially alter the power requirements.

3.2 Room Sizing

Keep in mind that all of the stated room dimensions are external NOT internal.

In order to calculate this you must add the width and length dimensions as well as

the height and floor spacers to determine the height.

Example: A Coldroom 2.6m long x 2.6m wide x 2.2m high will occupy…

External Room Width: 2.6 m

External Room Length: 2.6 m

External Room Height: 2.2 m

…A total of 2.6 meters in width by 2.6 meters in length by 2.2 meters in height

(260cm width x 260cm length x 220cm height)

The above specifies the minimum required space for installing the Coldroom size used

in the example but having more space is always a good idea.

Since it is thermally more efficient to NOT have the actual coldroom in contact with

other walls or structures we would, in this case recommend having the following

space: 2.75 m x 2.75m x 2.45 m. (25cm must be allowed in ALL cases above the

room, to allow for air flow.)

Installation

ATTENTION: Always wear eye protection when handling beams, posts and other PVC

components. PVC flakes will fall from within the coldroom components and can cause

injury and/or discomfort.

5.0 Floor

After you’ve made sure that you have the necessary space for installation and that all

the components on the packing list have arrived and are in good shape, you are ready

to start the actual set up process.

5.1 Floor Panels

Floor panels will always have an off-white side and a coated side. For standard floors

we apply a black phenolic resin coating over plywood.

• Floor panels come in lengths of: 80cm, 120cm, 160cm, 200cm & 240cm.

• Their width will always be 80cm or 120cm.

• Floor panels are 85mm thick.

5.2 Installing the floor panels

Material needed:

• Floor panels

• Allen wrench - found inside the Accessory (KITCMA) Box

Select floor panel(s) and position on floor where room is to be constructed, and in the

correct direction.

If your Coldroom contains various floor panels, start at a corner and move outward

according to the layout provided. When placing the second panel next to the first, align

them as indicated on the diagram below and lock them to each other.


7

To interlock the floor panels, take the Allen wrench and insert it into the cam-lock hole

on the coated side of the floor and twist about 45º clockwise. Stop tightening as soon

as you feel some resistance.

You should not have to twist the wrench more then 45º to 90º (max). When you feel

resistance simply stop and try to pull the two panels apart from each other to test

whether or not the cam-lock actually hooked to the panel next to it.

NOTE: Do not try to tighten the adjacent cam-lock on the second panel.

For every cam-lock pair that becomes aligned, only one needs to be twisted into the

locked position.

Please view the below image to better understand the concept behind the cam-locks.

Once you have the all floor panels in place and locked them onto one another, you will

be ready to put the floor beams in place.

5.3 Floor Beams

Once all the floor panels are laid out in place you may start placing the floor beams

around them according to the layout provided.

Floor beams serve as the attachment point for the walls and come in the following

lengths: 40cm, 80cm, 120cm, 160cm, 200cm and 240cm.

The floor beams have a height of 11.5cm and the same width as the panel being used.

5.4 Installing the floor beams

Material needed:

• Floor beams

• Allen wrench - found inside the Accessory (KITCMA) Box.

When setting the first floor beam you should be aware that it will stand 3cm taller than

the floor panel.


8

Start by aligning the first floor beam with the cam locks on one side of the floor panels.

Once you have aligned the cam-locks simply lock the beam into place just as you

tightened the floor panels to each other.

Attach all the floor beams to the floor panels as indicated in the diagram below.

6.0 Walls

After you’ve made sure that the floor panels and floor beams are all interlocked and

sturdy, you will be ready to raise the walls into position. The wall panels and corner

posts will be raised at the same time but first you must distinguish them from ceiling

panels and ceiling beams.

In the following section you will find information on how to properly raise the corner

posts, wall panels and door(s) into position.

6.1 Corner Posts

Corner posts are meant to provide an attachment point for two perpendicular wall

panels to grab onto at each corner.

They can often be confused with ceiling beams but are easily identified if you note the

following:

Unlike ceiling beams, the distance from each edge of the Corner post (beam) to the

middle of the first cam-lock is NOT 20cm. However the actual distance will vary greatly

and cannot be identified within this text. Also worthy of noting is the fact that the

actual distance will be different at each end of the corner post.

• Corner posts have a square cross section that is 85mm x 85mm

• Their length will span the entire external height of the coldroom (minus the

spacers).


9

6.2 Wall Panels

Wall panels and ceiling panels are exactly the same in every way. You must take note

of the distribution and placement of the panels on the provided layout. Any panel that

is longer than the internal height of the coldroom can automatically be considered a

ceiling panel.

Also worth noting is that unlike the floor panels which contain cam-locks every 40cm

(and 20cm from each edge), the wall and ceiling panels have cam-locks which start

20cm from each edge but are then placed 80cm apart.

For the rooms with wall panels of 220cm in length, the uppermost cam-lock will

rest 40cm from the top edge. This panel can NOT be applied upside down!

The bottom of the panel MUST contain a cam-lock 20cm from the bottom edge in order

to align properly with the other panels.

6.3 Installing the Wall Panels & Corner Posts

Material needed:

• Corner posts

• Wall panels

• Door


Setting up the walls and corner posts requires 2 people minimum, as does setting up

the ceiling, so please have someone ready to assist you from this point onward!

ATTENTION: Always wear eye protection when handling beams, posts and other PVC

components. PVC flakes will fall from within the coldroom components and can cause

injury and/or discomfort.

The first step is to have someone hold up a corner post while you verify that the

midpoint of the first cam-lock slot is 20cm above the floor beam since the first cam-

lock on the wall panel starts 20cm up from the lower edge.

While the corner post is being held up and you have verified that its first cam-lock will

align correctly with the wall panel; raise the wall panel up and rest it on the floor beam

or plate with the cam-lock holes facing the inside of the coldroom.

Use the Allen wrench to tighten the panel to the floor beam or plate first and then to

the corner post.

When done try to pull the corner post off the wall panel to test whether the cam-lock

actually grabbed onto the post properly. Afterward try to raise the wall panel to verify

that the panel also grabbed onto the floor beam or plate.


10

The next wall panel raised should be the perpendicular panel that will lock onto the

same corner post. Work outwards from these panels until the walls are complete.

Move around the room, connecting wall panels and upright connectors as necessary.

IMPORTANT: When installing a Slide-in Refrigeration system with the room, be sure

to locate the panel on which the Slide-in system will mount. This is determined by

which best suits the installation.

Un-box the Slide-in refrigeration system and install it as per the instructions with the

unit along with the guidelines in Section….. “Zanotti Slide-in Installation”.

7.0 Fitting the Door

The door(s) should be treated as if it were a wall panel and set up in its place

accordingly.

NOTE: Doors are shipped in the locked position with the keys taped onto the inside of

the door leaf. Please remove the keys from the door before completing the walls!

If you have decided to complete all the walls and ceiling and save the door for last, you

might end up with a room with no way of getting in! In this case an extra key will have

to be ordered so please remove the keys from the door before raising it into place.

Support the single panel in the upright position.

While doing this position the door in correct position and connect to the other side of

the upright connector, thus creating a 90° corner section.

When connecting the door, make note that the door panel includes the floor connector

which needs to be connected to the floor panel.


11

7.1 Doors and Freezer rooms

All doors (intended to be used on freezers at < 0 ºC) contain a heating cord that heats

the portion of the frame that comes into contact with the rubber from the door leaf so

that it will not freeze into place and damage the rubber.

NOTE: For Freezer rooms the door heater chord will need to be hooked up

to your standard line current by a qualified electrician.

8.0 Ceiling

IMPORTANT NOTE: If you are installing a Slide in Refrigeration unit to the room, it

must be installed prior to the roof being attached. Refer to Page 15.

Ceiling beams and panels are the next things to install before the finishing touches can

be applied. Once again, please ensure you wear adequate eye protection when raising

the ceiling beams into place so that PVC flakes do not fall into your eyes.

8.1 Ceiling Beams.

Ceiling beams are meant to provide an attachment point shared by the wall and ceiling

panels. They can often be confused with corner beams since they too have a square

cross section whose width is the same as the panel thickness.

Ceiling beams come in the following lengths: 120cm, 160cm, 200cm, and 240cm.


12

8.2 Installing the ceiling beams.

Material needed:

• Ceiling beams


Setting up the ceiling beam is as simple as laying them on top of the wall and

tightening the cam-locks from the wall panel so that it grabs onto the beam.

Position the ceiling connectors on top of the wall panels with the connecting slots

facing into the room. Connect all ceiling connectors in place, noting that they will fit

tightly into position and may require a small amount of force to push into place

After you have aligned and secured the ceiling beam try to raise it from the wall to

ensure that all the cam-locks have properly latched onto it. Work your way around the

room until all the ceiling beams have been placed according to the layout provided with

your coldroom.

The diagram below shows the recommended order in which the room should be

constructed once the floor is down. It may be preferred to install the roof beams

before both corner posts are positioned as shown in the diagram.


13

8.3 Ceiling Panels:

Ceiling panels, due to the nature of their purpose, are often longer than wall panels.

They should always be installed exactly as depicted by the provided diagram.

Their structural strength is designed to support one man and a toolbox. Of course the

weight of men and tool boxes can vary greatly. However, the actual maximum weight

allowed also depends on the thickness of the panel as well as the length.

Please contact your direct supplier for specific information.

Ceiling panels come in the following widths: 40cm, 80cm and 120cm.

8.4 Installing the ceiling panels:

Material needed:

• Ceiling panels


1 person holds the first ceiling panel in its appropriate location at the end of the

coldroom making sure that the cam-lock holes face the inside of the coldroom while

the other person tightens the cam-locks so that they grab onto the ceiling beam.

After positioning the 1st ceiling panel into place, take remaining ceiling panels and

position and lock into place ensuring all cam-locks are locked into position.

All ceiling beams must be supported on at least two sides before weight can be applied

onto it. (Support offered by other panels is not considered sufficient.)

Because of this, the ceiling panels often transverse the entire width of a coldroom.

For example: if you order a coldroom that’s 160cm x 240cm you will most likely

receive two 120cm x 160cm panels to stretch across the Coldrooms width.


14

8.5 Silicon Sealing the room

Upon completion of the modular room installation you should now seal any areas that

may require it, specifically the sealing between the panel joints.

• Freezer Rooms - Silicon must be used to seal ALL joints.

• Cool Rooms – Silicon sealing is at the discretion of the installer apart from

the floor which must be sealed along with any gaps.

NOTE: All construction surfaces are different therefore each room will assemble

differently. Small gaps may be present and must be sealed accordingly. A good test

once the room is built is to close the door and look for any places where light is visible.

Additional Room Components 9.0 Door Bells

Where a customer requests it, Bromic supply a Door Bell with the Modular room kit.

These are generally a standard designed manually operated Door Bell which fit to the

outside of the cold room door, with a key through to the inside where the bell can be

operated.

Installing Door Bells

Material needed:

• Door

• Bell with key

• Drill or hole saw

1. Firstly determine position on the door where the Bell is to be mounted and

mark where hole is to be made for “key”.

2. Drill the hole and mount the Bell assembly according to mounting requirements.

9.1 Cold Room Coving (Internal only)

Local area Health codes may require Internal Coving to be installed.

Where requested by the Customer Bromic supply aluminium coving in lengths of 6.5m.

The number of lengths provided with the room is dependant on the room size.

If upon arrival at a room installation and you are advised internal coving is required

please contact Bromic.

Installing Coving

Material needed:

• Coving

• Corner Clips

• Hack-saw
